A plic tion rnnez 7 Claims.

. his invention. relates to a collapsible cart for transporting a golf bag'ancli'its contents.

i Carts'oi this generalcharacter arewelrknown and have been disclosed'in various forms. However many of these are cumbersome; both when set up and collapsed; someare complicated to a' vision; of a cart arrangedto receive securely-a-golf' bag for transportation over thecoursc. but which maybe collapsed forstorage in therear of an automobileor "the luggage compartment thereof,

or in any other location where space is ata I premium. Another" object is to providea collapsible cart 'asaforesaid from which the-bag need-hotbe disunited when-the cart is collapsed.

Still another object is to provide a collapsible toand automa-tically locked in extended position during a single movement of the actuatingmemher. 7 a

Referring to Figs. 1 to 3; the cart comprises a principal member it preferably of light Weight tubing, extending-vertically over its principal extent, and bent forwardly and. then downwardly atitslower end to forman -extension LI- andafoot 12', this latter being equipped'with a rubber shoe i3 to protect the surface upon which the cart In some instances the" cart as aforesaidin which the wheelsare moved 1 50 er aLNQ- 3 05 39;

For

-, contracts in a straight configuration (Fig. will be clear that the wheels will be automatically retracted under such spring tension upon reterference. drawn upwardly by the handle [8 the chain 52, for example, will leave the wheel 6'! just before ;the spring 65 moves into contact therewith.

(Fig. 3), as Well as fore and aft (Fig. 1).

3, reducing the friction of the chains 52 and 52a over their respective sheaves and for esthetic considerations, the same may be sheathed by spirally wound or tubular plastic or like material of common construction and as shown.

Extending between spring posts 63 and 64, secured to the housing 42 and support 32 respectively, is a tension spring 65 adapted in certain positions thereof to be guided around a grooved wheel 61 freely rotatable on a post 68 carried on a bracket 69 of the support arms 33 and 33a. When the wheels 45 and 45a are extended the spring 65 is stretched around the wheel 61 '(Fig.

4) and when the wheels are retracted the spring It lease of tension in the chains. 7

In the case of the chains 52 and 52a, these,

when the wheels are extended, are positioned as seen in Fig. 4, and, when the wheels are retracted, pass from the sheaves 5t and 5411. over the wheels 61 and 61a. The construction and arrangement of the parts is such that the wheels 61 and 61a serve to guide either the springs 65 and 65a, or

thechains 52 and 52a, one at a time without in- Stated otherwise, as the chains are From the foregoing it will have become clear that in collapsed condition the cart is substantially narrower transversely than when set up Setting up of the cart is accomplished by a single motion,

namely the simple lifting of the handle i=8 to .horizontal position whereat it is automatically 5 1 locked by latch 28 dropping into its slot. To col- -lapse the cart the latch 28 is tripped whereupon the springs 65 and 65a are free to retract the -wheels, and as clearly seen in Figs. 4 and 5. To

steady the cart during activation of the handle l8 there may be provided a projecting member H upon which ones foot may be pressed.

While I have shown a particular embodiment of my invention, it will be understood, of course,

that I do not wish to be limited thereto since many modifications may be made, and I therefore contemplate by the appended claims to cover any 'such modifications as fall within and scope of my invention.

the true spirit Having thus described my invention, what I joint interconnecting each said support to said 'frame for swinging movement of said supports over an angle of substantially 180 from an extended position exteriorly of the maximum widthwise dimension of said frame to a retracted position interiorly of said dimension, a pair of linkages interconnecting each said support to said handle for joint actuation of said wheels about said knuckle joints from a retracted to an extended position and vice versa upon movement of said handle, and means for biasing said wheel supports to retracted position.

2. A cart as recited in claim 1 in'which each 7 Number said linkage comprises a cable-like member and guide sheaves for said member supported on said frame.

3. A- cart as recited in claim 2 in which said member comprises chain;

4. A collapsible golf bag cart comprising a frame, means for supporting the bag on said frame, a handle for propelling the cart pivotally mounted on said frame, a pair of wheel supports one disposed at each side of said frame, a wheel rotatably carried on each said support, said frame including a transversely extending member terminating at its ends in forwardly directed arms, a pivotal connection between each said arm and a wheel support, a linkage interconnecting said supports and said handle for rotating said supports about said pivotal connection in one sense, and biasing means intermediate each said arm and its associated support for rotating said supports in the opposite sense, and means for locking said handle against the urging of said biasing means.

5. A cart as recited in claim 4 in which said linkage comprises a flexible elongated member and guide sheaves for said member mounted on said frame.

6. A collapsible golf bag cart comprising a principal vertically disposed frame member, a transverse frame member secured thereto and terminating at each end in forwardly directed arms, an elongated handle for propelling the cart hingedly connected by one end adjacent the upper end of said vertical frame member and operable to active and inactive positions, means for releasably locking said handle in active position, a pair of supports one individual to each said arm and pivotally connected thereto, a wheel rotatably mounted on each said support, tension means interconnecting each said support and its associated arm for biasing each wheel to a retracted position, a cable-like member interconnecting each said support to said handle, means carried on said frame members for guiding said cable-like member whereby movement of said handle toactive position is effective, through said cable-like member to actuate said wheels to said extended position against the bias of said tension means. a

'7. A collapsible golf bag cart comprising a frame, means for supporting the bag on said frame, a handle for propelling the cart movably interconnected to said frame, a pair of wheel supports each pivotally mounted at laterally opposite sides of said frame, each support having a wheel rotatably mounted thereon, a linkage interconnecting said supports and handle for pivoting said supports over an arc of substantially to move said supports and wheels from a retracted to an extended position, bias means intermediate said frame and supports for urging said supports and wheels from extended to retracted position, and means for locking said handle against the urging of said bias means.
